The invention discloses a digital filter wire grid imaging method used for eliminating a scattered radiation influence. The method comprises the following steps of S1, using data in an area of interest to calculate an adaptive logarithmic curve so as to correct image brightness; S2, carrying out anti-white processing on the image on which the brightness correction is performed; and S3, carrying out virtual filter wire grid processing on the image after the anti-white processing so as to acquire an output image. By using the method of the invention, a problem that thick body position image quality is not good can be solved; simultaneously, a problem that an effect is not stable during an actual usage process is effectively solved too; stability and the image quality are greatly increased; and under the condition that a patient radiation dosage level is reduced, diagnosis quality is guaranteed.
